Subject[PATCH v2] PCI: Remove unused includes and superfluous struct declaration
Date
Remove <linux/pci.h> and <linux/msi.h> from being included
directly as part of the include/linux/of_pci.h, and remove
superfluous declaration of struct of_phandle_args.

Move users of include <linux/of_pci.h> to include <linux/pci.h>
and <linux/msi.h> directly rather than rely on both being
included transitively through <linux/of_pci.h>.
